"We just decided that it didn't hold together well enough to yield a series," NBC Entertainment chairman Bob Greenblatt said. "It looked beautiful and original and creative, but it just all ultimately didn't come together… it just didn't ultimately creatively all work."

Deadline reports that Greenblatt further elaborated on the pilot's failure, explaining that it "didn't get the mix right".

"We felt great about that cast, but we tried to make it not just a sitcom," he said. "We tried to make it an hour, which ultimately has more dramatic weight than a half-hour. It's hard to calibrate how much weirdness vs supernatural vs family story [to include]."

However, the network boss refused to rule out another attempt at a Munsters revival in the future.

"I won't say we won't do another version of The Munsters again," Greenblatt announced.
